@MikeGDTE It would be best to reach out to your IT admin team or Microsoft as this issue is with Outlook and how mail is being sent.
These invitations and RSVPs are governed by that application and mail service. Zoom isn't a part of that process.
To put it in perspective, Zoom = creating meeting details and URL, Outlook/O365 = sending the email and invitations (with RSVP)
